Fence



FIG. 1 is a top plan view of a fence showing my new design;

FIG. 2 is a front elevation view thereof, the rear being a mirror image thereto;

FIG. 3 is a right side view, the left side being a mirror image thereto; and,

FIG. 4 is a bottom plan view thereof.

The broken lines are for illustrative purposes only and form no part of the claimed design. 

I claim the ornamental design for a fence, as shown and described.
